Hehe... No one can hack my wifi connection because I am using Netgear Arlo security with my router firmware. And Netgear Arlo support also provides me the advance security to protect all types of theft with my Network IP. If you want to secure your IP and network connection to try out this feature with him. He has defined a DNS issue with certain Internet Service provider that is causing a connection to the Arlo app to fail. I also find the nice guys who reveal your network issue with full-on security and to aware of the issue with push notification at the using of time. I think everyone has Arlo pro to avoid the same issue with Netgear router and use theft free network.
Not all Android phones or tables can crack a WPS PIN. You'll need to have a device that has a Broadcom bcm4329 or Broadcom bcm4330 wireless chipset and it must be rooted. Your phone should also have a Cyanogen ROM for the best success. If your phone fits these qualifications you can now do this.
